UNITED STATES PATENT 'OFFICE.

SAMUEL FRANCIS \VILLIAMS, OF SAN FRANCISCO, CALIFORNIA.

SINK-SIRAINER.

SPECIFICATION forming part of Letters Patent N 0. 706,621, dated August 12, 1902. Application filed September 3, 1901.' Serial No. 74,174. (No model.)

To all, who??? it nuty concern:

Be it known that I, SAMUEL FRANCIS WIL- LIAMS, a citizen of the United States, resid-- ing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Sink-Strainers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichfit appertains to make and use the same.

My invention relates to improvements in sinks, more especially the strainers thereof.

Having for its object particularlyto simplify construction, lessen cost of manufac ture, and facilitate and expedite the using of the device or invention, it consists of the combination and arrangement of parts, in-.

eluding their construction, substantially as hereinafter more fully disclosed,and specifically pointed out by the claim.

In the accompanying drawings, illustrating the preferred embodiment of my invention,-( Figure 1 is a plan view. Fig. 2 is a vertical sec-' and the same yet remain intact and be protected.

In carrying out my invention I provide for the sewer-pipe drain a strainer 1, as is customary, said strainer, however, diifering from those heretofore in use, as herein presently called to attention. Said strainer comprises a preferably circular plate or disk 1, having, preferably, a radial arrangement of apertures 1 therein, oblong, as shown,or otherwise in outline. Said plate or disk has a central opening 1, adapted to permit the insertion therethrough of the usual screwthreaded collar or end piece of a hose (not shown) to provide for effecting connection between said plate and said. hose,-as presently disclosed. Cast with the under side of said plate or disk is a pendent sleeve 2, having an inner screw-threaded surface or wall whose screw-threads are continued along the surface or wall of the opening 1 of said plate for the purpose as aforesaid, whereby, in event of the sink becoming clogged up or needing flushing, water under pressure may be introduced therein through said hose, the same being connected up with a suitable water-supply and said screw-threaded sleeve. A screw-threaded plug 3, suitably adapted, as

shown, for convenient manipulation by a screw-driver or otherwise, is inserted into ing arrangement of apertures 1 of the plate l er to be. inoved out of coincidence therewith for the purposewell' understood. To

permit the ready movement of the slide or plate 4, it is provided with a stud 5, projecting through a slot 5 in the plate 1 and adapted to be conveniently grasped by the fingers. l A

"Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A sink strainer of the character described, comprising a perforated plate or disk having a central opening with a screw-threaded edge and a screw-threaded pendent sleeve in continuation of said opening, having upon its outer surface a flange, a second perforated plate or slide arranged upon said sleeve be low said first plate and carried by said flange, and means for actuating said second plate, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
